Membership reinstatement without permission, 3 months after cancelation

I have cancelled my Bonitas membership in February 2022 and I received and email 3 months later (May) saying that my membership has been reinstated without my permission. I am currently an active member on a different medical aid scheme for the past 3 months and I therefore can not have 2 active medical aid memberships on my name.

I have contacted Bonitas numerous times over the past couple of days (which is costing me a lot in airtime) only to receive the same email everyday in the afternoon which does not resolve my issue.

I already have a confirmation certificate for the termination of my Bonitas membership from February but that seems to be pointless as it is constantly ignored.

please can someone from the right department contact me urgently to resolve this matter before the debit order goes off and I will be left to deal with costly and unnecessary bank charges.
